Instance

1, year-month-day

The code is as follows	Copy Code
echo Date (' y-m-j '); 2007-02-6 echo Date (' y-n-j '); 07-2-6

Uppercase Y represents the year four digits, while lowercase y represents the two digits of the year;
Lowercase m represents the number of months (with leading), while lowercase n indicates no leading month number.

The code is as follows	Copy Code
echo Date (' y-m-j '); 2007-feb-6 echo Date (' y-m-d '); 2007-02-06

The uppercase M represents the 3 abbreviated characters of the month, while the lowercase m represents the number of the month (with leading 0);
J with no uppercase, only lowercase J indicates the date of the month, no leading o, or lowercase D if a month with a leading is required.

The code is as follows	Copy Code
echo Date (' y-m-j '); 2007-feb-6 echo Date (' Y-f-js '); 2007-february-6th

Uppercase M represents the 3 abbreviated characters of the month, while uppercase F indicates the full written English of the month. (No lowercase f)
Uppercase S represents the suffix of the date, such as "St", "nd", "rd", and "th", depending on the date number.

Summary:
Indicates that the year can be in uppercase Y and lowercase y;
Indicates that the month can be in uppercase F, uppercase M, lowercase m, and lowercase n (two ways of representing characters and numbers, respectively);
Indicates that the day can be in lowercase d and lowercase j, and uppercase s represents the suffix of the date.

2, Hours: minutes: seconds

By default, the PHP interpretation is displayed as "Greenwich Mean Time", which differs from our local time by 8 hours.

The code is as follows	Copy Code
echo Date (' g:i:s a '); 5:56:57 am echo Date (' H:i:s A '); 05:56:57 AM

The lowercase g represents a 12-hour system without a leading 0, while the lowercase h indicates a 12-hour system with a leading 0.
When using the 12-hour system, it is necessary to indicate that in the afternoon, lowercase a represents the lowercase "am" and "PM", and uppercase a denotes uppercase "AM" and "PM".

The code is as follows	Copy Code
echo Date (' g:i:s '); 14:02:26
